Struct Ruler 

pub struct Ruler { /* private fields */ }

A horizontal/vertical axis with fixed-size, nonoverlapping labels.

Implementations

impl Ruler

pub fn horizontal(scale: Scale, baseline: f64) -> Self

Creates an X-axis at the supplied Y coordinate.

pub fn vertical(scale: Scale, baseline: f64) -> Self

Creates a Y-axis at the supplied X coordinate.

pub fn ticks(self, count: usize) -> Self

Selects uniform ticks including endpoints; valid count is 2..=256.

pub fn nice_ticks(self, count: usize) -> Self

Selects at most the supplied number of aligned ticks; valid budget is 2..=256.

pub fn tick_length(self, length: f64) -> Self

Replaces finite nonnegative tick length.

pub fn line_width(self, width: f64) -> Self

Replaces positive finite axis/mark width.

pub fn font_size(self, size: f64) -> Self

Replaces label font size in (0,4096].

pub fn label_size(self, size: Size) -> Self

Replaces explicitly authored positive label dimensions.

pub fn color(self, color: Color) -> Self

Replaces axis and label color.

pub fn unit(self, unit: impl Into<String>) -> Self

Replaces the formatting suffix, without changing physical units.

pub fn node(&self) -> Result<Node>

Builds nodes with two-decimal default numeric labels.

pub fn node_with_labels( &self, formatter: impl FnMut(f64) -> String, ) -> Result<Node>

Eagerly formats once per tick and returns text plus one union fill. The common fill prevents axis/mark intersections from multiplying alpha.

Trait Implementations

impl Clone for Ruler

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Ruler

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
